Television legend Bob Newhart will soon bring his dry comedic stylings to "The Big Bang Theory," but his guest spot -- set to air May 2 -- could turn into the start of something bigger.
Newhart, 83, will play Professor Proton, a character modeled after classic TV science types Mr. Wizard and Bill Nye, who Sheldon (Jim Parsons) and Leonard (Johnny Galecki) loved as kids.
"Sheldon and Leonard watched (Professor Proton's show) religiously, and it influenced them to go into science," Newhart told TV Guide. "When they find out he's doing appearances, they book an appointment."
But that's just where the fun begins.
According to the star, the episode ends in a way that potentially "sets it up for me to return a couple more times next season."
That's good news for fans and good news for Newhart, who seemed to enjoy his time on the set, if a recent photo with his family is anything to go by.
"The Big Bang Theory" airs Thursdays at 8 p.m. on CBS.
